Turn tracing into callbacks for each syntax element, with default
callbacks to match current trace_headers behaviour for debug. Move
the construction of bit strings into the trace callback, which
simplifies all of the read and write functions.

Thank you for the response.
With all due respect, my email is NOT about the RTSP standard, or the
vendor specifics.
FFmpeg code already does the necessary stuff by sending either
GET_PARAMETER or OPTIONS.

It includes various Windows-specific headers when compiling
for Windows and these sometimes cause issues: E.g. winbase.h
defines IGNORE, which clashes with a macro used in the Matroska

This header provides fallback defines for var

winbase.h defines IGNORE and is included via bzlib.h when compiling
for Windows. So rename this macro to NOTHING.
Also rename the muxer macro for consistency.
